Impact
During a security audit of Helm's code base, security researchers at Trail of Bits identified a bug in which the alias
field on a Chart.yaml
is not properly sanitized. This could lead to the injection of unwanted information into a chart.
Patches
This issue has been patched in Helm 3.3.2 and 2.16.11
Specific Go Packages Affected
helm.sh/helm/v3/pkg/chartutil
Workarounds
Manually review the dependencies
field of any untrusted chart, verifying that the alias
field is either not used, or (if used) does not contain newlines or path characters.
